ive just tried setting up 2.5 butchers tubless, using stans fluid on dt swiss FR600 rims. They wont hold air..
rims are almost new but i cleaned them with 92% alcohol and used gorilla tape all the way to the inside edges and stuck that tape down hard. seated the beads with a compressor @ 55 psi overnight. I used roughly four ounces of sealant in the back tire. They seemed like they were holding air fine for the last few days and this morning I checked them and the rear is completely flat, the front has probably 15psi..
what a pita!!

other than the occasional pressure loss from sitting 3-4 weeks of no use, they held up awesome and they never burped or unseated on me. the only thing i didnt like was the weight of the dual ply tires, took a lot of pedalz to get it up to speed.
the valves are from a miata racing company, 949 racing. cutting them down is pretty easy.

i imagine the dh casing schwalbes would be a good canidate to try? theyre folding, correct?
that is very odd that they worked for a couple of days and then shit the bed... you didnt leave them at 55psi the whole time did you?
You definitely want a tape strip in there serving more than just a rim strip. Beyond just helping seal it, some tire/rim combos need to be 'built up' a little so that any big gaps between the two get filled/supported.
If you're all the way to the edge, your bead might not be seated all the way because the tape is keeping the tire rolled in a little bit.. Cover as much as you can on the rim but leave 2mm back from the wall. Worth a shot.
